Book excerpt: The authors present a measurement of the angle? of the Unitarity Triangle with a Dalitz analysis of neutral D decays to K{sub S}??− from the processes B° → {bar D}°(D°)K*° ({bar B}° → D°({bar D}°){bar K}*°) with K*° → K+?− ({bar K}*° → K−?+). Using a sample of 371 x 106 B{bar B} pairs collected with the BABAR detector at PEP II, they measure the angle? as a function of r{sub S}, the magnitude of the average ratio between b → u and b → c amplitudes. Combining this result with the available information on r{sub S}, they obtain? = (162 ± 56){sup o} or (342 ± 56){sup o} and r{sub S}
